BIOL 127 Lecture Notes - Lecture 16: Bog, Species Evenness, Coevolution
Document Summary
Interaction is not established and not important in affecting the distribution and abundance of other species in the group: association, assemblages with described characteristics in a particular habitat, e. g. species in a peat bog. Ways to categorize biological communities (various species in a common location): species diversity, species richness and evenness, food web structure. Food chain length: 3-5 links based on thermodynamic considerations. Extent of omnivory: animals that obtain chemical energy from plants and animals. Compartmentalization: organization of sub-units where interactions are strong but between the interactions are weak - food web. Compound community: a supraunit consisting of component communities that interact to varying extents. Guild: a group of species that exploit a particular resource in a similar way. The species do not need to be closely related taxonomically. An anthropomorphic viewpoint of how resources are being utilized by the insects.
